Efficient energy transfer has been demonstrated in an Er/Yb co-doped phosphorus doped silica fiber for the first time. This has indirectly allowed the use of reliabIe, high power AlGaAs diode laser arrays as the semiconductor pump source through the use of a diode-pumped Nd:YAG (DPL) laser operating at 1064 nm. Small signal gains of 40 dB and output powers of 69 mW (+18.4 dBm) have been observed with a single DPL Bi-directional pumping with two DPL's has yielded an output power of 145 mW (+21.5dBm).
